American Autowire Universal Highway 15 Plus Wiring System.

American Autowire's new-and-improved wiring system includes your favorite original features, along with improvements like a built-in LED flasher and a new high amp alternator and main power connection kit. The Universal Highway 15 Plus Wiring System (510825) retains the features you love with modernization that will benefit novices and experts alike.

American Autowire has taken measures to ensure you won't have to buy additional products to complete the system. For example, the built-in LED flasher will support LED turn signals without an extra purchase. The system also includes further connectors and wiring to support a four-headlight system. And, longer neutral safety wires are available to accommodate cars with console shifters. These changes have been made for your convenience, preventing the need for add-on purchases. 

Features and Benefits:
- Built-In LED Flasher Supports LED Turn Signals 
- New High Amp Alternator and Main Power Connection Kit
- Longer Neutral Safety Wires for Cars with Console Shifters
- Additional Ignition Circuit to Support Aftermarket Components
- Improved Ignition Switch (Uses a Square GM-Style Key)
- GXL/XLPE GM Color-Coded Wire
- Easy-to-Read Wire Labeling Every 3-4 Inches
- Self-Locking Screw Clamp Interface
- Ignition, Headlight and Dimmer Switches Included

Of course, the new changes also help the system conform to more modern vehicles for an easier install and reliable performance. A back up light feed and power wires make the harness easier to install, and an additional ignition circuit is provided to support aftermarket components. An improved ignition switch is supplied, along with a mating connector and four additional accessory and ignition terminals. Lastly, the high amp alternator and main power connection kit will allow you to use high amp alternators. This connection kit provides an improved level of fuse protection for the panel and charging system. It will use 6ga wire and two 175amp Megafuses.

You can still expect to see the original features that made the Highway Series the most popular wiring system on the market! You'll benefit from a self-locking screw clamp interface, GXL/XLPE GM color-coded wire and American Autowire’s signature gauge cluster disconnect. You'll receive the G-10 composite panel base, which measures 4.5”L x 4.5”W x 3.5”H, and nylon 6/6 panel components.
